What Next After Failed Septal Ventricular Tachycardia Ablation?

Indian Pacing and Electrophysiology Journal, 2012
Ablation of ventricular tachycardia (VT) by conventional radiofrequency ablation can be impossible if the ventricular wall at the targeted ablation site is very thick, as for example the ventricular septum.

Case Report: Application of Thoracoscopic Clamp Radiofrequency Ablation on Atrial Tachycardia Originating From Right Atrial Appendage After Catheter Ablation Failure

Frontiers in Cardiovascular Medicine, 2021
Atrial tachycardia originating from the right atrial appendage has a higher probability of failure of catheter ablation. Here we report a case of a 13-year-old boy with incessant tachycardia, complicated by heart enlargement, and heart failure ...

Reverse Remodeling of the Mitral Valve Complex After Radiofrequency Catheter Ablation for Atrial Fibrillation: A Serial 3-Dimensional Echocardiographic Study.

Circulation Cardiovascular Imaging, 2019
BACKGROUND Mitral regurgitation is frequently complicated with atrial fibrillation without apparent organic changes in the leaflet, which occasionally improves after successful radiofrequency catheter ablation.

Transient complete heart block following catheter ablation of a left lateral accessory pathway. [PDF]

, 2019
A 16-year-old female with symptomatic Wolff-Parkinson-White (WPW) syndrome underwent catheter ablation of a left-sided lateral accessory pathway. The accessory pathway was eliminated with the first ablation lesion; however, the patient immediately ...

Surgical repair of an esophageal perforation after radiofrequency catheter ablation for atrial fibrillation

Indian Pacing and Electrophysiology Journal, 2019
Recent reports have described the incidence of atrioesophageal fistulas (AEF), often resulting in death, from radiofrequency (RF) catheter ablation of atrial fibrillation (AF).1 Cases of esophageal perforation without concomitant AEF have not been ...

Effect of Isthmus Anatomy and Ablation Catheter on Radiofrequency Catheter Ablation of the Cavotricuspid Isthmus [PDF]

Circulation, 2004
Background— Cavotricuspid isthmus (CTI) characteristics are rarely documented when comparing catheters in radiofrequency ablation (RFA) of atrial flutter (AFL). Our objectives were (1) to evaluate the impact of CTI morphology and length on ablation procedures and (2) to compare the efficacy of an 8 ...

Radiofrequency ablation of ventricular premature contraction originating from a native coronary cusp after transcatheter aortic valve replacement

Journal of Arrhythmia, 2017
We describe a case of radiofrequency ablation of ventricular premature contraction (VPC) originating from the left ventricular outflow tract after transcatheter aortic valve replacement. The VPC origin was the native aortic valve annulus between the left

Randomized trial of conventional transseptal needle versus radiofrequency energy needle puncture for left atrial access (the TRAVERSE-LA study). [PDF]

, 2013
BackgroundTransseptal puncture is a critical step in achieving left atrial (LA) access for a variety of cardiac procedures. Although the mechanical Brockenbrough needle has historically been used for this procedure, a needle employing radiofrequency (RF)
